Friendship, Humor, Mathematics, Math 

The beguiling second entry in the innovative shape trilogy by multi-award-winning, New York Times best-selling duo Mac Barnett and Jon Klassen.This book is about Square. Square spends every day taking blocks from a pile below the ground to a pile above the ground. This book is also about Square’s friend Circle. Circle thinks Square is an artistic genius. But is he really? With the second story in a trilogy of tales about Triangle, Square, and Circle, Mac Barnett and Jon Klassen nudge readers toward a more well-rounded way of looking at things. Understated and striking in its simplicity, this funny, thoughtful offering from two of today’s most talented picture-book creators emphasizes the importance of keeping your eyes — and your mind — open to wonder where others see only rubble and rocks. - from Amzon
